The Toyota Sienna may not be one of the first models anybody associates with the SEMA Auto Show, but Toyota’s resident people mover has been a showstopper in Las Vegas over the past few years. Anybody remember the R-Tuned Concept from last year’s show? How about the SpongeBob Edition? While we’re at it, let’s not forget about the Swagger Wagon Supreme from 2010, one of the most outlandish builds we’ve ever seen at SEMA. This year, Toyota’s booth at SEMA brought the Extreme Sienna. While it’s not as mind-blowing as the Swagger Wagon, it still upholds the oftentimes audacious nature of SEMA.

Regardless of what you think of the Sienna, you can’t deny that it’s an incredibly popular car among aftermarket tuners. This time around, Toyota brought in Rick Leos, hot rod builder extraordinaire from Real Time Automotive to put his aftermarket touch on the Sienna. “We wanted to go to a place no one else would think of with this build,” Leos said, referring to what he and his team decided to do on the minivan. “This Extreme Sienna is our contribution to the van culture movement that’s happening right now. People are showing a lot of vision and adapting vans to serve for almost any purpose. We wanted to take this idea all the way to the next level.”

That “next level” can be interpreted in so many different directions, but as far as Leos and Real Time Automotive were concerned, it was a license to go crazy on the Sienna, which is exactly what they did to the minivan, most notably the infusion of luxury to the vehicle’s interior. The result is as impressive a build for the Sienna as we’ve seen in a long time. Even SpongeBob can’t say anything about it.

Exterior

It wouldn’t be a proper SEMA-built Toyota Sienna without some massive modifications on the exterior, would it? Leos and Real Time Automotive certainly put in the work to make the Extreme Sienna look right at home in Las Vegas, giving it a wide body kit thats defined by bigger panels throughout the body to go with plenty of carbon fiber details. The revised front fascia looks particularly gnarly and the ground effects do their part in adding some muscle to the minivan’s overall looks while also creating the look of a van that’s seemingly kissing the ground even as it’s sitting idle. A new set of gold wheels combine with the blue body finish to channel the van’s inner Subaru while the rear diffuser, spoiler, and dual exhaust finish off the busy and admittedly sporty look of the Extreme Sienna.

Interior

As exhaustive as the exterior of the Extreme Sienna looks, the interior upgrades are where the real party’s at. It has a cabin that’s drowning in fine leather and custom upholstery. There are reclining seats too, the kind that are more commonly seen in the interior of a Learjet. The lap of luxury doesn’t end their either as the cabin was also treated to a refrigerator and parquet floor tiles. These features combine with tech offerings like Wi-Fi connectivity and a Bluetooth speaker to create what can only be described as a luxury office space on four wheels. Oh, and the whole van can be controlled by an iPad, right down to the air ride suspension system that manipulate the van’s height and handling characteristics by a simple swipe or press on that iPad.

Drivetrain

Note: Standard Toyota Sienna drivetrain shown here.

The Extreme Sienna has the cosmetic and aerodynamic makings to stand out at an event like SEMA. Unfortunately, the upgrades in those departments, as exhaustive as they are, represent the only significant modifications on the overall makeup of the minivan. That means that the Sienna's 3.5-liter V-6 engine still produces 266 horsepower and 245 pound-feet of torque, representing no changes to the capabilities of that V-6. The good news is that with the new carbon fiber components, the van should be light enough to improve on its 7.6-second, 0-to-60-mph time. Either way, the van’s power and performance numbers are more than enough to justify the large amount of cosmetic upgrades that Rick Leos and Real Time Automobiles

Conclusion

Considering the things we've seen from the Toyota Sienna over the years at SEMA, the Extreme Sienna isn't actually that extreme by the definition of the word. On the contrary, it's actually a good representation of what a well-tuned Sienna should be. I'm not a big fan of the overdone aero kit, but everything else, from the color scheme to the luxurious interior, is what I'd want to see from a heavily modified Sienna.
